A20 Mobile TDLAS Gas Leak Survey System for Natural Gas Distribution Networks

A20 Mobile Gas Leak Survey System for Natural Gas Networks

Efficient pipeline inspection requires more than gas detection alone. The A20 combines mobile methane sensing, geographic positioning, imaging, and data analysis to help gas operators identify potential leakage areas and manage inspection activities across extensive distribution networks.

Turn Driving Routes into Inspection Data

The A20 collects methane detection data during vehicle patrols and associates measurement results with geographic locations. Its mapping interface presents patrol routes, gas concentration readings, anomaly notifications, and imaging information together, giving operators a clearer overview of field conditions.

Selective Laser Sensing for Methane Surveys

Using Tunable Diode Laser Absorption Spectroscopy (TDLAS), the A20 measures methane through its characteristic laser absorption wavelength. The selective detection principle helps distinguish methane signals from common atmospheric components and supports gas leak surveys in environments affected by road traffic and vehicle exhaust.

AI-Assisted Data Screening

Field measurements can be affected by changing environmental conditions and background interference. The A20 incorporates AI-assisted anomaly filtering to help screen suspicious signals and reduce unnecessary alerts. Inspection history provides additional information for reviewing recurring anomalies and identifying areas that may require further investigation.

Optimize Patrol Coverage and Risk Assessment

Route planning helps inspection teams organize survey activities across designated pipeline areas. By retaining inspection histories and location-linked readings, the A20 supports comparisons between patrols, follow-up inspections, and data-informed maintenance decisions.

Designed for Practical Field Applications

The A20 is intended for urban gas distribution surveys, natural gas pipeline patrols, and methane leak investigations around gas infrastructure. Its integrated approach helps transform routine vehicle patrols into structured inspection workflows, supporting more efficient use of field personnel and inspection resources.
